Hofsstaðir in Garðabær City Area is a significant Viking Age farm site dating back to around 870-930. This longhouse, believed to have housed 20-30 people, was most likely inhabited until the 12th century. It was discovered in 1986 during construction when a kindergarten was to be built on this site.  In 1989 further excavation was made and from 1994-2000 a thorough archaeological excavation was carried out, supervised by The National Museum of Iceland..  It's 8x30 metres on the outside with a floor surface of 170 sq.m, which makes it one of the largest longhouses discovered in Iceland.Archaeological excavations unearthed approximately 300 items, including an unusual bronze broach, spindle whorls, and loom weights from a weaving room, highlighting its status as a wealthy farmer’s home. Turf walls now mark the site's boundaries, and a multimedia exhibition offers visitors insights into Viking life. Hofsstaðir remains open to the public year-round, free of charge, and is a unique historical gem nestled within the town of Garðabær.
